Re: concat 2 binary files?

I want to manipulate binary files.

this was just a test to concatinate 2 text files but it said
file_put_contents was undefined.  the second parameter is suppoed to be
'mixed data', no idea what that is.


The file_put_contents() function is only supported on PHP v >= 5; the indication mixed data means that it can be anything from a scalar to an array.

But this was just a test anyway since file_get_contents uses strings,
can someone just give me the code to concat 2 binary files? I'll be
manipulating the files before I concatinate them, so putting the data
into 2 arrays of bytes 1st would be best.


An alternative for file_put_contents on PHP 4.x would be to apply fopen with ``wb'' as the switch and fputs for writing:

$fp = fopen("somenewfile", "wb");
fputs($fp, $data_1 . $data_2);
fclose($fp);

Since file_get_contents() is binary safe, the binary data will be untouched and the merge successful, provided that the binary data actually can be merged this way...
